Abstract
Appareil de traitement de liquide ou système comportant un lit de traitement de liquide qui est régénéré par son passage dans une solution formée par la dissolution d'un solide dans un liquide. Un système de commande automatique amorce un cycle de régénération au besoin. Des indices sont fournis relativement au contenant dans lequel se trouve la matière solide, de façon que des indices pertinents illustrent la quantité de matière solide qui se trouve dans le contenant. En fournissant ces indices au circuit de commande, celui-ci enregistre la quantité de matière solide restante et sonne l'alarme lorsque la quantité de matière solide restante descend en deçà d'un niveau préétabli.
